|phenology=Flowering May–Jul.
|habitat=Sagebrush-mountain brush, pinyon-juniper, ponderosa pine, and spruce-fir communities, on fine-textured, often saline, seleniferous substrates.

|distribution=Ariz.;Colo.;N.Mex.;Utah;Wyo.
|discussion=<p>Variety haydenianus from the Wasatch Plateau in Utah has been confused by some workers with the similarly pale-flowered var. major, but the flowers are consistently smaller, much more numerous, and the fruits smaller than in var. major.</p>
